Thermodynamics of a relativistic Fermi gas in a strong magnetic field

The thermodynamical properties in the grand canonical ensemble for a relativistic spin -1/2 ideal gas including both the particles and anti-particles are investigated in the presence of strong constant homogeneous magnetic field. The authors calculate the magnetization and the static magnetic susceptibility for very strong fields at high temperatures, for which they present numerical results in the special case for equal numbers of particles and anti-particles.
